- Abstract:
- In order to study the growth index, water use efficiency, yield and component factors of oil sunflower under different ridges and furrows and sprinkling irrigation treatments, and compare the advantages of different sprinkling irrigation treatments, the effects of different irrigation treatments on oil sunflower growth characteristics, yield and utilization efficiency of irrigation water were analyzed by conventional methods of crop growth indexes and HD2 soil moisture meter. The results showed that ridged planting and furrow sprinkling irrigation had better effect of collecting water and preserving soil moisture, which was beneficial to the growth of oil sunflower. Under the appropriate irrigation quota condition(T3), the plant height, stem diameter, leaf area index and dry matter accumulation of oil sunflower were large. Compared with the control(CK), the yield of oil sunflower in two years increased by 4.07% and 8.70%, water saving was 11.0% and 14.1%, the utilization efficiency of irrigation water increased by 21.1% and 22.1%, and the water productivity was over 9.0 yuan/m3. To sum up, in this experimental conditions, compared with the traditional effect of the culture sprinkler irrigation, ridge tillage furrow sowing sprinkler irrigation treatment can effectively use of irrigation water during whole growth period, improve soil moisture, make oil sunflower grow much stronger, can improve the yield and irrigation water use efficiency, and is a kind of economic and feasible, easy to promote water-saving irrigation technology.
